The significant difference between VMARC and things like PKZIP (ARC, etc)
is the file system environment for which they are targetted.  VMARC is an file
compaction and archive utility for VM/CMS.  It understands a few file system
basics such as LRECL and RECFM.  PKZIP and friends are utilities for the PC
environment, where, IMHO, the file system is featureless.

A PKZIP implementation for VM would be mostly useless except for handling
PC-type files on the mainframe.  Then again, VMARC for the PC would be
overkill.  (If I remember correctly, the definition for ZOO includes file
system "features", but I suspect they are not widely implemented.)

P.S.  By the way, I thing someone stated that ARCUTIL (another program for VM)
supported *creating* ZIP files.  It does not.  It supports un-ZIP functions.
